Abstract (en)
[origin: EP2665257A1] An image sensor (1) comprising: an array (2) of pixels logically organized in rows and columns, the outputs of the pixels being connected to column lines (COLx) connectable to an array of buffers (3) via a routing block (10), the buffers being connected to an array of A/D convertors (4), the routing block (10) having a group of switches (6, 7) for reading sub-picture data, whereby the values of at least two rows of the sub-picture are distributed over the analog-to-digital-convertors before digitizing them in parallel. The entire sub-picture (21) may be digitized in one step. The routing block (10) may comprise an analog bus (9).
